Description

Technical Field

[0001] This utility model relates to the technical field of electric vehicle or motorcycle accessories, specifically a circuit board mounting structure, a combination switch, and a handle. Background Technology

[0002] The combination switch for electric vehicles or motorcycles, as the central control module of the vehicle, has multiple button functions and is the main module for realizing human-machine interaction. In existing combination switches, separate wiring harnesses are generally required to enable communication between the various modules.

[0003] This wiring method leads to a chaotic internal wiring harness structure and unstable connections. During use, the internal wiring may twist or be compressed, potentially damaging the circuit. Furthermore, repeated adjustments to the wire harness position are required during installation to avoid interference, severely impacting installation efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a circuit board mounting structure, combination switch, and handle that can reduce discrete wiring harnesses and improve installation reliability and efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit board mounting structure, comprising: At least two circuit boards, each of which is stacked along the thickness direction; An inter-board electrical connection assembly is disposed between two adjacent circuit boards, and the two adjacent circuit boards are connected to each other by plugging in the inter-board electrical connection assembly; One of the circuit boards extends outward from its edge to form an extended mounting area, which is used to mount buttons.

[0006] As a further improvement of this utility model, the circuit board comprises at least three pieces.

[0007] As a further improvement of this utility model, it also includes a detachable encapsulation housing, which includes a base and a cover plate. The base and the cover plate are detachably connected, and the circuit board is disposed between the base and the cover plate.

[0008] As a further improvement of this utility model, the base extends a support structure corresponding to the extended installation area, and the support structure is used to support the extended installation area.

[0009] As a further improvement of this utility model, it also includes a top cover, which is connected to the base by a snap-fit ​​connection. The top cover has a positioning groove corresponding to the position of the cover plate, and the cover plate is positioned in the positioning groove.

[0010] As a further improvement of this utility model, the cover plate is an elastic waterproof cover plate.

[0011] As a further improvement of this utility model, a connecting part extends from the top cover, and a mounting groove is provided on the connecting part. A button is installed in the mounting groove by a snap-fit ​​connection, and the button is electrically connected to the circuit board through a plug wire.

[0012] As a further improvement of this utility model, the top cover is provided with an operation window corresponding to the button position on the circuit board, and the elastic waterproof cover is sandwiched between the circuit board and the top cover, so that the button is triggered by pressing the elastic waterproof cover through the operation window.

[0013] A combination switch is also provided, comprising the circuit board mounting structure described in any of the preceding claims.

[0014] A handle is also provided, including the aforementioned combination switch and handlebar.

[0015] The beneficial effects of this invention are that by stacking at least two circuit boards along their thickness direction and interlocking them with an inter-board electrical connection component, it replaces the traditional method of relying on discrete wire harnesses for electrical connections between circuit modules. This eliminates the problems of unreliable connections caused by wire harnesses crossing and twisting in a limited space, and also reduces the steps of repeatedly adjusting the wire harness position during installation, thus improving assembly efficiency. Furthermore, the extended mounting area formed by extending outward from the edge of the circuit board integrates the button mounting position into the circuit board body, further expanding the flexibility of button placement within a limited space.

[0018] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figure 1-4 As shown, a circuit board mounting structure according to this embodiment includes: At least two circuit boards 1, each circuit board 1 is stacked along the thickness direction; An inter-board electrical connection assembly is disposed between two adjacent circuit boards 1, and the two adjacent circuit boards 1 are connected to each other by plugging in the inter-board electrical connection assembly; One of the circuit boards 1 extends outward from its edge to form an extended mounting area 2, which is used to mount the button 3.

[0020] In the above structure, at least two circuit boards 1 are arranged sequentially in the thickness direction. Unlike the traditional approach where circuit boards 1 or buttons 3 are distributed along the housing contour, this stacked arrangement fully utilizes the thickness space inside the combination switch housing, reducing the planar footprint. Adjacent circuit boards 1 are directly connected via an inter-board electrical connection component. The male and female terminals of the component are respectively located on opposite sides of the upper and lower circuit boards 1. When the two circuit boards 1 are stacked in the thickness direction, the male terminal inserts into the female terminal to achieve conductivity. This electrical connection component simultaneously provides power supply and signal communication, completely replacing the multiple discrete wires required between circuit boards 1 in traditional solutions. Since the inter-board electrical connection component automatically completes the insertion process during stacking, installation is significantly simplified compared to handling wire harnesses, where each wire's path needs to be identified, straightened, and its position fixed. Furthermore, the stacked circuit boards 1 are in a relatively fixed position, preventing loosening or breakage due to vibration or torsion during use, thus improving long-term reliability. The extended mounting area 2, which extends outward from the edge of the circuit board 1, allows the button 3 to be directly mounted on this area. The button 3 and the circuit board 1 body are electrically connected through the internal wiring of the circuit board 1, eliminating the need to connect the button 3 to the distant circuit board 1 via an external wire.

[0021] To accommodate the integration needs of more functional modules, in one optional solution, circuit board 1 consists of at least three pieces.

[0022] When three or more circuit boards 1 are used, each circuit board 1 is still stacked sequentially along the thickness direction, and adjacent circuit boards 1 are connected by inter-board electrical connection components, which can further increase the expansion functions. The control unit on the circuit board 1 can communicate with each module or external module using CAN communication, further reducing discrete wiring harnesses.

[0023] To provide physical encapsulation and protection for the circuit board 1, a detachable encapsulation housing 4 is further included. The detachable encapsulation housing 4 includes a base 41 and a cover plate 42. The base 41 and the cover plate 42 are detachably connected, and the circuit board 1 is disposed between the base 41 and the cover plate 42.

[0024] When the base 41 and the cover plate 42 are closed, they form a closed or semi-closed receiving space, in which the stacked circuit boards 1 are placed. The base 41 and the cover plate 42 protect the internal circuit boards 1 and the inter-board electrical connection components, preventing external dust and debris from entering the circuit area.

[0025] To enhance the structural stability of the extended installation area 2, further optimization can be achieved by extending a support structure 411 from the base 41 to the extended installation area 2. The support structure 411 is used to support the extended installation area 2.

[0026] When the support structure 411 extends from the base 41, the top surface of the support structure 411 contacts and supports the lower surface of the extended mounting area 2. This restricts the downward deformation of the extended mounting area 2 when subjected to the operating force of the button 3, and the operating force is transmitted to the base 41 through the support structure 411. The support structure 411 changes the extended mounting area 2 from a cantilevered state to a state supported at both ends (one end is connected to the circuit board 1 body, and the other end is supported by the support structure 411), improving the structural stability of the extended mounting area 2 during long-term use. This solution solves the problem that the extended mounting area 2 extending from the edge of the circuit board 1 may deform during use due to lack of support.

[0027] In order to achieve tool-free assembly and accurate positioning of cover plate 42, in some options, top cover 43 and base 41 are connected by snap-fit, and top cover 43 is provided with positioning groove 431 corresponding to the position of cover plate 42, and cover plate 42 is positioned in positioning groove 431.

[0028] During assembly, first, the cover plate 42 is placed on the base 41, and then the top cover 43 is fastened from top to bottom. The locking structure on the top cover 43 and the corresponding locking structure on the base 41 engage and lock together, completing the overall sealing of the enclosure without the need for screws or other additional fasteners. The pre-set positioning groove 431 on the top cover 43 matches the edge contour of the cover plate 42. When the top cover 43 is fastened in place, the cover plate 42 is naturally guided into the positioning groove 431 and held in that position, preventing it from shifting during subsequent use.

[0029] In order to provide waterproofing while sealing, the cover plate 42 is further designed to be a flexible waterproof cover plate 42, which may be a silicone pad.

[0030] After the base 41 and the cover 42 are closed, the elastic waterproof cover 42 is clamped between the upper surface of the circuit board 1 and the mounting position of the cover 42. Its elasticity creates a certain compression seal between the cover 42 and the base 41. The material of the elastic waterproof cover 42 itself is impermeable, preventing external moisture from seeping into the area of ​​the circuit board 1 through the joint surface between the cover 42 and the base 41. Since the elastic waterproof cover 42 simultaneously performs the encapsulation function and the waterproof sealing function, there is no need to set an additional independent sealing ring or gasket inside the encapsulation housing, simplifying the overall structure.

[0031] To achieve the additional integration of button 3 on the top cover 43, the following optimization method can be selected: a connecting part 432 extends from the top cover 43, and a mounting groove 433 is provided on the connecting part 432. Button 3 is installed in the mounting groove 433 by a snap-fit ​​connection, and button 3 is electrically connected to circuit board 1 through a plug wire.

[0032] This solution allows the button 3 in the mounting slot 433 to be accurately positioned, improving integration. Even when using a plug-in cable, the high level of integration will not cause confusion.

[0033] In order to enable the button 3 on the circuit board 1 to still be operated after encapsulation, a top cover 43 is further included. The top cover 43 has an operation window 434 corresponding to the position of the button 3 on the circuit board 1. An elastic waterproof cover 42 is sandwiched between the circuit board 1 and the top cover 43 so that the button 3 is triggered by pressing the elastic waterproof cover 42 through the operation window 434.

[0034] The operation window 434 on the top cover 43 faces the button 3 on the circuit board 1, and the corresponding area of ​​the elastic waterproof cover 42 is located between the button 3 and the operation window 434. When a user presses down through the operation window 434 from the outside (e.g., with an external operating device), the pressure acts on the elastic waterproof cover 42, causing it to elastically deform and transmit the pressure downwards to the button 3, triggering it. The operation window 434 allows the top cover 43 to fully cover the package while maintaining an external access path to the button 3 on the circuit board 1. The elastic sealing surface formed by the elastic waterproof cover 42 below the operation window 434 maintains a local waterproof seal while withstanding the pressure deformation, ensuring that the overall waterproofness of the package is not compromised by the operation window 434.

[0035] To enable the application of the above-mentioned circuit board mounting structure in combination switches, a combination switch is also provided, including any of the above-mentioned circuit board mounting structures.

[0036] To achieve the integration of the combination switch and the vehicle handlebar, a handlebar is also provided, which includes the aforementioned combination switch and handlebar.

[0037] In summary, in the application of the circuit board mounting structure of this utility model, all circuit boards 1 are stacked along the thickness direction, and adjacent circuit boards 1 are connected by inter-board electrical connection components. This allows power and signal transmission between circuit boards 1 to be achieved entirely through direct inter-board connection, eliminating the need for any discrete wiring harnesses within the housing. An extended mounting area 2 extending from the edge of the circuit board 1 provides an integrated button 3 mounting location, supported by a support structure 411 on the base 41. The base 41 and cover 42 of the detachable encapsulation housing 4 enclose and protect the circuit board 1. The top cover 43 is fixed to the base 41 by a snap-fit ​​connection and positioned by a positioning groove 431. When the cover 42 is made of a flexible waterproof material, it provides both encapsulation and waterproof sealing. An operation window 434 on the top cover 43 allows external access to trigger the button 3 below by pressing the flexible cover 42 without compromising the waterproof seal. The connecting part 432 extending from the top cover 43, together with the mounting groove 433, provides an additional mounting position for the external button 3, which is reliably electrically connected to the internal circuit board 1 via a plug-in cable.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
